Amer Haddadin tells RadarOnline.com that Suleman has owed him a $450,000 balloon payment on the loan since October 9. As RadarOnline.com has reported, he’s threatened to evict her more than once since then.

She has a new deadline of December 31 to pay up and because Haddadin has no indication from Suleman that she’ll have the money in time, he has his lawyer ready to pounce with both a lawsuit and eviction proceedings on January 3.

In a complicated series of financial transactions, Haddadin revealed to us that he actually holds a mortgage from an unnamed bank for the property.

He transferred title to Suleman in exchange for more than a million dollars, but she hasn’t paid him according to their contract. In August, Nadya transferred title on the property to her attorney Jeff Czech.PHOTOS: Octo-Mom On A Date

“She’s current on the monthly payments of $4,060,” Haddadin says. “The balloon payment is the problem.”

Haddadin refused to reveal his own plans for paying the mortgage he owes on the property. “It’s my business if I let it go to the ground or if I pay back the bank.PHOTOS: Hot Celebrity Moms

“But Nadya needs to get out if she’s not able to pay. If she can’t pay, she has no business being in my house.”
